DIN EN 12354-1:2000-12

The document describes calculation models designed to estimate the airborne sound insulation between rooms in buildings, primarily using measured data which charactrize direct or indirect flanking transmission by the participating building elements and theoretically derived methods of sound methods of sound propagation in structures elements. It describes the principles of the calculation schema, lists the relevant quantities and defines its applications and restrictions. It is intended for acoustical experts and provides the framework for the development of application documents and tools for other users in the field of building construction, taking into account local circumtances.
